Sounds like a good sized festival. Two of the ones here in Colorado that I go to reach to 30 to 75,000 visitors, not including participants. I agree that the large ones seem to become less intimate so that it becomes just a big crowd. I would like to hear more about what is showcased there, athletics and music aside.

Sorry about the long delay in replying, unfortunately, I do not have an answer, I know it runs for three days, ending with a parade of over 3000 pipers & drummers through Dunoon, the local town. This an area familiar to many Americans, as it used to be home to a USN Polaris submarine base for many years.I hate admitting how little I know about these games, sorry I couldn't be of more use, I'll make an exception this year, & be sure to get some photos to post on the site of the final days events,

Here in the US< I believe, the largest maybe Pleasanton (and the oldest). Clan MacLea (Livingstone) will have a tent there this year. I've heard previously their attendance can reach over 90K. Although they and Grandfather Mtn Games, coming up this coming weekend seem to think they're the largest, not the other... hard to see everything when they're that spread out.
